Skin, model and textures of the world
The skin changes the appearance of the character. It does not replace the textures of the entire map or add new gameplay features. Before uploading a picture, decide which model it is made for: Classic/Wide or Slim. The classic version of the hand has a width of four pixels, while the thin one has three. Inappropriate choice of model is especially noticeable on the hands. To draw your own, first save the original template to compare the position of the parts after checking.
How to upload a skin to Java Edition
Open the official Minecraft Launcher, select Minecraft: Java Edition on the left and go to the Skins tab. Click New Skin, set a name and select a model. Via Browse, specify the PNG with the skin image, then save it and select Save and Use. An ordinary character photograph is not a finished scan. Before entering the server, look at the result in the game from all sides: this will make it easier to find mixed up parts of the picture.
